JPG fills transparency with white. HEIC exports the first decoded image. Metadata, color profiles, and animation may change. Always keep your originals.
Reduce image weight with measurable results
Compression here means re-encoding an image with chosen output settings. WebP is selected initially; JPG is another option. You can also reduce dimensions. The result shows the actual byte sizes and percentage change for each file, including increases.
When to Use This Tool
- Try to fit a photo within an upload size limit.
- Compare several quality settings before sharing.
- Reduce both dimensions and encoding size for a batch.

Frequently Asked Questions
Helpful answers before you convert.
Can I request an exact output file size?
No. There is no target-byte control. Adjust quality or dimensions, convert again, and compare the measured result.
How is the percentage change calculated?
The displayed change compares output bytes with original bytes and is rounded to a whole percentage. A bigger output is labeled larger, not presented as a saving.
Why can 100% quality still change an image?
The value is an encoder quality setting, not a promise to preserve every pixel. JPG and this WebP export can still be lossy; resizing also changes pixels.
How do I compress a transparent PNG?
Try WebP with a lower quality or smaller dimensions. Choose PNG if lossless encoding is required; its quality slider is inactive. JPG will replace transparency with white.
